I actually have the problem with all of the XBox linked apps that they crash my computer entirely. They'll work for a bit but then freeze up the computer beyond any reasonable way of starting it again and I'm forced to manually restart the entire computer.
It makes it particularly bad that no matter what tests I may run nothing comes back with having anything wrong with it and the other apps I have never crash at all. I have issues with a couple actual games I have installed, but that's on a different company, not Microsoft.
I liked to play Solitaire and Minesweeper, things like that, but I seem to be forced to play in reality now... You know, actual cards and Battleship.
